| How can one access the data cache? $0, $N ... do not appear to hold the data.
The spec also says:
${lookup{<key>} <search type> {<file>} {<string1>} {<string2>}}
${lookup <search type> {<query>} {<string1>} {<string2>}}
...
If the lookup succeeds, <string1> is expanded and replaces the entire item.
During its expansion, the variable $value contains the data returned by the
lookup. Afterwards it reverts to the value it had previously ...
